Pit bulls

Can anyone research back several years to find a count on pit bull attacks? I seem to recall five or six now in the recent past. This is absolutely insane.

Definitely two or three dog attacks in the past two or three months.

I have had close calls with these dogs three times in my life, once while walking with my dog and two others while visiting at their homes. And the owners just smile and say, 'Don’t worry he’s friendly."
